136 Infotainment System
updated periodically, provided that the map
information has changed and the vehicle has
a relevant service plan.
Over-the-Air-Vehicle Map Updates
If equipped, the infotainment system can
receive map updates over the air. Map
updates occur within a 161 km (100 mi)
radius around the home address on file. This
boundary will adjust over time based on
driving patterns. The vehicle uses a
Cloud-connected service to receive the date
and downloads it to the system’s onboard
SD card, if equipped. A data plan or
compatible mobile device hotspot is
required. The SD card is required for
navigation system function.
When a map update is available, a prompt
will appear on the infotainment display.
Once the update is accepted, it will
download and run in the background
without interruption any infotainment
functions. The download will carry over
ignition cycles, stopping and starting where
it left off. The updates can be set to
download automatically.See www.gmnavdisc.com for details on
ordering, purchasing, and installing a new or
replacement SD card. Features are subject to
change. For more information on this
feature, see my.gmc.com/learn.Database Coverage Explanations
Coverage areas vary with respect to the
level of map detail available for any given
area. Some areas feature greater levels of
detail than others. If this happens, it does
not mean there is a problem with the
system. As the map data is updated, more
detail can become available for areas that
previously had limited detail. See
Map Data
Updates 0135.
Voice Recognition
If equipped, voice recognition allows for
hands-free operation within the navigation,
audio, phone, and weather applications. This
feature can be started by pressing
gon the
steering wheel or touching
gon the
infotainment display. However, not all features within these areas
are supported by voice commands.
Generally, only complex tasks that require
multiple manual interactions to complete
are supported by voice commands.
For example, tasks that take more than one
or two touches, such as a song or artist to
play from a media device, would be
supported by voice commands. Other tasks,
like adjusting the volume or seeking up or
down, are audio features that are easily
performed by touching one or two options,
and are not supported by voice commands.
In general there are flexible ways to speak
commands for completing the tasks.
If your language supports it, try stating a
one-shot command, such as
“Directions to
address
while stating the address during the
command. Another example of a one-shot
Destination Entry command is, “Directions to
Place of Interest at
commands do not work, try saying, “Take
me to Place of Interest” or“Find address”
and the system will walk you through by
asking additional questions.

Infotainment System 137
Hybrid Speech Recognition
If equipped, this feature helps distinguish
words by using Internet-based information
along with the system’s voice recognition
database. This allows you to speak more
naturally when using voice recognition.
Using Voice Recognition
Voice recognition becomes available once
the system has been initialized. This begins
when the ignition is turned on. Initialization
may take a few moments.1. Press
gon the steering wheel controls
to activate voice recognition.
2. The audio system mutes and the system plays a prompt.
3. Clearly speak one of the commands described in this section.
A voice recognition system prompt can
be interrupted while it is playing by
pressing
gagain.
Once voice recognition is started, both the
infotainment display and instrument cluster
show the selections and visual dialog
content. These displays can be turned on or
off in the Tutorial Mode under Settings
0 147. There are three voice prompt modes
supported:
.Informative verbal prompts: This type of
prompt will provide more information
regarding the supported actions.
.Short prompts: This type of prompt will
provide simple instructions about what
can be stated.
.Auto informative prompts: This type of
prompt plays during the first few speech
sessions, then automatically switches to
the short prompt after some experience
has been gained through using the
system.
If a command is not spoken, the voice
recognition system says a help prompt.
Prompts and Infotainment Displays
While a voice recognition session is active,
there may be corresponding options
showing on the displays. A selection can be
made by manually touching the option,
or by speaking the number for the option to
select. Manual interaction in the voice
recognition session is permitted. Interaction
during a voice session may be completed
entirely using voice commands while some
manual commands may expedite a task. If a
selection is made using a manual control, the voice recognition dialog will progress in
the same way as if the selection were made
using a voice command. Once the system
completes the task, or the session is
terminated, the voice recognition dialog
stops.
An example of this type of manual
intervention is touching an entry of a
displayed number list instead of speaking
the number associated with the entry
desired.
Canceling Voice Recognition
.Touch or say
“Cancel”or“Exit” to
terminate the voice recognition session
and show the display where voice
recognition was initiated.
.Pression the steering wheel controls
to terminate the voice recognition session
and show the display where voice
recognition was initiated.
Natural Language Commands
Most languages do not support natural
language commands in sentence form. For
those languages, use direct commands like
the examples shown on the display.

Bluetooth (Overview)
The Bluetooth-capable system can interact
with many mobile devices, allowing:

.Become familiar with the features of the
mobile device. Organize the phone book
and contact lists clearly and delete
duplicate or rarely used entries.
If possible, program speed dial or other
shortcuts.
.Review the controls and operation of the
infotainment system.
.Pair mobile device(s) to the vehicle. The
system may not work with all mobile
devices. See “Pairing”later in this section.
Vehicles with a Bluetooth system can use a
Bluetooth-capable mobile device with a
Hands-Free Profile to make and receive
phone calls. The infotainment system and
voice recognition are used to control the

Driving Information
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
cell phone.
{Warning
Taking your eyes off the road too long or
too often could cause a crash resulting in
injury or death. Focus your attention on
driving.
Refer to the infotainment section for more
information on using that system and the
navigation system, if equipped, including
pairing and using a cell phone.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The first step in driving
defensively is to wear the seat belt. See
Seat Belts 027.
